CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. §119 to Korean PatentApplications Nos. 10-2011-0088944 and 10-2011-0104591, filed on Sep. 2,2011 and Oct. 13, 2011, respectively, in the Korean IntellectualProperty Office, the disclosure of which is incorporated herein byreference in its entirety.

TECHNICAL FIELD

The following disclosure relates to a French nail sticker, and moreparticularly to a French nail sticker capable of being attachedto/detached from a release liner without any damages on the sticker mainbody and applied with ease to nails.

BACKGROUND

In general, when users intend to improve the shapes of their nails, theyapply manicure on their nails to perform nail art with a desiredpattern. However, nail art including applying manicure to nails requiresa complicated and delicate procedure and is inconvenient due to the timeneeded for drying the applied solution. Particularly, in the case ofnail art, such as French nail art, including coloring the end portion ofa nail, it is required that each nail has a uniform area to whichmanicure is applied, and a smile line, which is a terminal line ofFrench nail art positioned at the side of a nail bed, is applied in auniform and constant manner. However, it is difficult for non-skilledpersons to carry out such nail art work by themselves. Moreover, evenwhen the user is a skilled person, carrying out French nail art manuallyand directly on her/his nails is problematic in that the shapes appliedto both hands by French nail art are not uniform depending on whetherthe user is right-handed or left-handed.

To overcome the above-mentioned problems, the users have asked atechnical specialist of nail art, working in a nail shop or the like, toimprove the shapes of their nails. However, when the users ask atechnical specialist to perform French nail art, they pay for the nailart work every time they need the service and thus they have burdenedthemselves with high cost.

Therefore, there has been a need for developing a French nail sticker sothat even non-skilled persons may form a uniform smile line of Frenchnail art and perform French nail art with a uniform shape by themselves.

DETAILED DESCRIPTION OF EMBODIMENTS

The advantages, features and aspects of the present invention willbecome apparent from the following description of the embodiments withreference to the accompanying drawings, which is set forth hereinafter.The present invention may, however, be embodied in different forms andshould not be construed as limited to the embodiments set forth herein.Rather, these embodiments are provided so that this disclosure will bethorough and complete, and will fully convey the scope of the presentinvention to those skilled in the art. The terminology used herein isfor the purpose of describing particular embodiments only and is notintended to be limiting of example embodiments. As used herein, thesingular forms “a”, “an” and “the” are intended to include the pluralforms as well, unless the context clearly indicates otherwise. It willbe further understood that the terms “comprises” and/or “comprising”,when used in this specification, specify the presence of statedfeatures, integers, steps, operations, elements, and/or components, butdo not preclude the presence or addition of one or more other features,integers, steps, operations, elements, components, and/or groupsthereof.

In general, French nail art is performed at the site of a free edge ofnail and is realized in a shape similar to the yellow line of a nail.The yellow line means a nail between the free edge of nail and thehyponychium and is not in contact with the skin. When carrying out nailart not over the whole nail plate but on a portion of nail, like Frenchnail art, it is difficult to define the boundary of a desired pattern.

The French nail sticker disclosed herein is provided to solve theabove-mentioned problem. Particularly, the French nail sticker disclosedherein allows even non-skilled persons to form a delicate pattern ontheir nails by themselves when the pattern is required to be formed on aportion of nail. In other words, the French nail sticker disclosedherein allows users to carry out French nail art with ease.

FIG. 1 is a planar view of the French nail sticker according to anembodiment, and FIG. 2 is a sectional view of the French nail stickeraccording to an embodiment.

The French nail sticker disclosed herein is broadly divided into asticker main body 120 applied to a nail, a release liner 110 protectingthe shape of the sticker main body 120, and a guide portion 130.Particularly, as shown in portion (a) of FIG. 1, the French nail stickerdisclosed herein is formed into the shape of the yellow line of a nail,and includes:

a sticker main body 120 having a convex free end 120 x and a concavehyponychium end 120 y opposite to the free end;

a release liner 110 disposed on the bottom surface of the sticker mainbody 120 and intended to be bound detachably with the sticker main body120; and

a guide portion 130 intended to be bound detachably with the top surfaceof the sticker main body 120 and including a grip portion 134 yprotruding toward the free end 120 x of the sticker main body 120.

The free end 120 x of the sticker main body 120 has a convex shape andis disposed at the free edge that is the terminal end of a nail whenapplied to the nail. In addition, the hyponychium portion 120 ygenerally corresponds to a smile line formed while carrying out Frenchnail art, and has a curvature in the same direction as the free end 120x.

The sticker main body 120 is applied actually to a nail and includes anadhesive component coated on the bottom surface thereof. Therefore, therelease liner 110 provided on the bottom surface of the sticker mainbody 120 serves to prevent contaminants, such as dust, from beingattached to the adhesive component formed on the sticker main body 120before applying the sticker main body 120 to a nail. Since the releaseliner 110 has release property, the adhesive component of the stickermain body 120 does not remain on the release liner 110 but is detachedeasily therefrom.

The guide portion 130 is attached to the top of the sticker main body120. Similarly to the sticker main body 120 detachable from the releaseliner 110, the guide portion 130 is detachable from the sticker mainbody 120. The guide portion 130 facilitates detaching the sticker mainbody 120 from the release liner 110 and attaching the sticker main body120 to a nail.

The guide portion 130 includes a guide film 134 and a second adhesivelayer 132, wherein the guide film 134 includes an adhesive region 134 xdisposed on the top of the sticker main body 120, and a grip portion 134y extending from the adhesive region 134 x and protruding out of thefree end 120 x of the sticker main body 120; and the second adhesivelayer 132 is adhered detachably to the top of the sticker main body 120on one surface thereof, and adhered and fixed to the bottom of theadhesive region 134 x on the other surface thereof.

The guide portion 130 is divided into the guide film 134 and the secondadhesive layer 132, and the second adhesive layer 132 is not formedtotally on the bottom surface of the guide film 134 but is applied onlyto the guide film 134 at the position to be bound with the sticker mainbody 120. In other words, the guide film 134 may be divided into theadhesive region 134 x having the second adhesive layer 132 coated on thebottom surface thereof, and the grip portion 134 y having no secondadhesive layer 132 applied thereto. The grip portion 134 y is held by ahand when it is required to detach the sticker main body 120 from therelease liner 110. In other words, when detaching the sticker main body120 from the release liner 110, it is possible to remove the stickermain body 120 from the release liner 110 with ease without scraping outthe sticker main body 120 manually or bending the release liner 110.Therefore, it is possible to prevent the sticker main body 120 frombeing damaged during the detachment of the sticker main body 120 fromthe release liner 110. For this, one surface of the second adhesivelayer 132 is adhered detachably to the top of the sticker main body 120and the other surface of the second adhesive layer 132 opposite theretois adhered and fixed to the bottom of the adhesive region 134 x. In thismanner, it is possible to maintain the second adhesive layer 132attached to the guide film 134, when the guide portion 130 is separatedfrom the sticker main body 120.

The adhesive region 134 x′ disposed on the top surface of the stickermain body 120 may be formed on a portion of the sticker main body. In avariant, as shown in portion (b) of FIG. 1, the adhesive region 134 x′may be formed in the same shape as the sticker main body 120 so as toprevent removal of the pattern printed on the sticker main body 120 orformation of scratches on the surface of the sticker main body 120.

As shown in FIG. 2, the sticker main body 120 includes: a first adhesivelayer 122 capable of being attached to/detached from the release liner110; and a base layer 124 disposed on the top of the first adhesivelayer 122 and bound firmly to the first adhesive layer 122.

Although the sticker main body 120 may be realized to have a designcapable of decorating a nail only with colors provided by the base layer124, the base layer 124 may further include an additional pattern orcolor to improve the appearance of the sticker main body 120. In otherwords, the sticker main body 120 may further include an additionaldesign layer 126 on the top of the base layer 124, and a top coat layer128. In this case, the guide portion 130 is attached to the top coatlayer 128 of the sticker main body 120. When the sticker main body 120has no additional design layer 126, the top coat layer 128 may bedisposed on the top of the base layer 124 so that it is positionedalways on the uppermost part of the sticker main body 120. In otherwords, the top coat layer 128 provided on the uppermost part of thesticker main body 120 may serve to protect the surfaces of the baselayer 124 or the design layer 126 disposed on the bottom of the top coatlayer 128.

In addition, when the sticker main body 120 has the top coat layer 128on the top surface thereof, it is possible to impart a gloss to thesurface of the design layer 126 and to improve the appearance of thesticker main body 120. Furthermore, the material forming the top coatlayer 128 may serve to maintain a certain degree of adhesion, whilefacilitating the separation between the sticker main body 120 and theguide portion 130 after the sticker main body 120 is attached to a nail.

The base layer 124 of the sticker main body 120 may be made of at leastone selected from polypropylene (PP), polyethylene (PE), polyvinylchloride (PVC), polyvinylidene chloride (PVDC), ethylene vinyl acetate(EVA), polyethylene terephthalate glycol (PETG) and polyurethane (PU).In other words, the base layer 124 may be formed of any one materialselected from PP, PE, PVC, PVDC, EVA, PETG and PU. In a variant, two ormaterials may be selected from PP, PE, PVC, PVDC, EVA, PETG and PU andblended at an adequate ratio to form the base layer 124. In addition,particular examples of the adhesives forming the first adhesive layer122 and the second adhesive layer 132 may include solvent-freeadhesives, such as acrylic-, urethane acrylic-, silicone-, epoxy- androsin-based adhesives, and solvent-based adhesives, such as acrylic-,urethane acrylic-based, silicone-based and epoxy-based adhesives.

As shown in FIG. 2, the guide portion 130 includes the guide film 134and the second adhesive layer 132. The guide film 134 includes anadhesive region 134 x disposed on the top of the sticker main body 120,and a grip portion 134 y extending from the adhesive region 134 x andprotruding out of the free end 120 x of the sticker main body 120. Thesecond adhesive layer 132 is adhered detachably to the top of thesticker main body 120 on one surface thereof, and adhered and fixed tothe bottom of the adhesive region 134 x on the other surface thereof. Inother words, the guide film 134 may be divided into the adhesive region134 x having the second adhesive layer 132 on the bottom surfacethereof, and the grip portion 134 y having no second adhesive layer 132applied thereto. Therefore, when attaching the sticker main body 120 toa nail, the grip portion 134 y having no second adhesive layer 132 isheld by a hand to separate the sticker main body 120 from the releaseliner 110.

When the adhesion between the second adhesive layer 132 and the stickermain body 120 is higher than the adhesion between the first adhesivelayer 122 and the release liner 110, merely pulling the grip portion 134y without direct contact with the sticker main body 120 allows thesticker main body 120 to be detached easily from the release liner 110.Therefore, it is possible to prevent deformation of the shape of thesticker main body 120 during the detachment of the sticker main body 120from the release liner 110.

Particularly, the adhesion between the second adhesive layer 132 and thesticker main body 120 may be 1.5-4 times higher than the adhesionbetween the first adhesive layer 122 and the release liner 110. Todetermine the adhesion, a Pull-Off Test according to ASTM D4541 is used.When the adhesion between the second adhesive layer 132 and the stickermain body 120 is below a level of 1.5 times higher than the adhesionbetween the first adhesive layer 122 and the release liner 110, thesticker main body 120 may not be detached from the release liner 110 butonly the guide portion 130 may be separated from the sticker main body120 depending on the direction in which the grip portion 134 y ispulled. In this case, it is required to hold the sticker main body 120directly by a hand to detach the sticker main body 120 from the releaseliner 110. Therefore, the first adhesive layer 122 provided on thebottom of the sticker main body 120 becomes in contact with the hand,resulting in a drop in adhesion or deformation of the appearance of thesticker main body 120. When the adhesion between the second adhesivelayer 132 and the sticker main body 120 exceeds a level of 4 timeshigher than the adhesion between the first adhesive layer 122 and therelease liner 110, the sticker main body 120 may be detached easily fromthe release liner 110 but the guide portion 130 may not be separatedeasily from the sticker main body 120 after applying the sticker mainbody 120 to a nail. In other words, a portion of the second adhesivelayer 132 disposed on the bottom of the adhesive region 134 x remains onthe sticker main body 120 as a residue during the separation between theguide portion 130 and the sticker main body 120, resulting indegradation of the appearance of the sticker main body 120. Therefore,according to an embodiment, the adhesion between the second adhesivelayer 132 and the sticker main body 120 may be 1.5-4 times higher thanthe adhesion between the first adhesive layer 122 and the release liner110.

As described above, to facilitate the separation between the secondadhesive layer 132 and the sticker main body 12 while maintaining apredetermined degree of adhesion between the second adhesive layer 132and the sticker main body 120, the French nail sticker may furtherinclude a top coat layer 128. The top coat layer may be made of a UVcoating agent, and a primer layer 134 a to which the second adhesivelayer 132 is adhered and fixed may be an acrylate-based resin. In otherwords, the top coat layer 128 and the primer layer 134 a are formed byusing materials capable of providing higher adhesion between the secondadhesive layer 132 and the primer layer 134 a as compared to theadhesion between the second adhesive layer 132 and the top coat layer128. In this manner, it is possible to prevent the residue of the secondadhesive layer 132 from remaining on the top of the top coat layer 128when the guide portion 130 is detached after applying the sticker mainbody 120 to a nail. Particular examples of the acrylate-based resin mayinclude, but are not limited to methyl methacrylate, methyl acrylate,ethyl methacrylate, ethyl acrylate, or the like.

In addition, the guide film 134 of the guide portion 130 includes:

a primer layer 134 a bound with the second adhesive layer 132 andremoved from the release liner 110;

a marking layer 134 b printed on the top of the primer layer 134 a andrepresenting the center of the sticker main body 120; and

a protective layer 134 c stacked on the top of the marking layer 134 b.

Particularly, after forming the primer layer 134 a on the top of thesecond adhesive layer applied to the sticker main body, a center linerepresenting the center of the sticker main body 120 may be printed onthe top of the primer layer as required, thereby forming the markinglayer 134 b. To prevent the marking layer 134 b from being delaminatedby external force, the protective layer 134 c may be stacked on the topof the marking layer. The protective layer 134 c may be formed of anepoxy resin, etc. In addition, a center line and a size mark may beformed on the guide portion 130. The center line represents the centerof the sticker main body 120 and the size mark represents the size ofthe sticker main body 120. Therefore, it is possible to check whetherthe sticker main body 120 is suitable for the user's nail or not beforeseparating the thin film of the sticker main body 120 from the releaseliner 110. In addition, it is possible to align the central portion ofthe nail with the center line of the sticker main body 120 beforeapplying the sticker main body 120 to the nail. As a result, it ispossible to apply the sticker main body 120 to an adequate position ofthe nail at once while avoiding a need for repeatingattachment/detachment of the sticker main body 120 several times. Inother words, according to the guide portion 130 provided on the top ofthe sticker main body 120, it is possible to prevent the sticker mainbody 120 from being damaged by detachment of the sticker main body 120from the release liner 110 and attachment of the sticker main body 120to a nail.

FIG. 3 is a block diagram illustrating the method for manufacturing aFrench nail sticker according to an embodiment.

The French nail sticker disclosed herein may be obtained by the methoddescribed hereinafter. As shown in FIG. 3, there is provided a methodfor manufacturing the French nail sticker, including:

stacking an adhesive and a base film to be bound with the adhesive onthe top of a release liner 110;

printing the shape of the sticker main body 120 on the top of the basefilm;

half-blade cutting the base film and the adhesive along the shape of thesticker main body 120 printed on the top of the base film;

removing the base film passed through the half-blade cutting from therelease liner 110 and forming the sticker main body 120 on the top ofthe release liner 110; and

forming a guide portion 130 on the top surface of the sticker main body120 formed on the top of the release liner 110.

First, the base film treated with an adhesive on the bottom surfacethereof is disposed on the top surface of the release liner 110. Next,the shape of the sticker main body 120 is printed on the top of the basefilm in a form to be realized as the design layer 126 of the stickermain body 120. Then, the remaining non-printed portion of the base filmand the printed portion of the base film are cut in the operation ofhalf-blade cutting. The cutting operation is carried out not by cuttingthe release liner 110 but by cutting the base film and the adhesivedisposed on the bottom surface of the base film. In other words,although the half-blade may penetrate through a part of the thickness ofthe release liner 110, it may not penetrate through the whole releaseliner 110. Therefore, when removing the base film after the half-bladecutting, the printed portion of the base film is still retained but thenon-printed portion is removed. In this manner, the sticker main body120 is formed.

After that, while only the sticker main body 120 is retained on the topsurface of the release liner 110, the guide portion 130 is attached tothe top surface of the sticker main body 120, thereby finishing themanufacture of the French nail sticker disclosed herein. Particularly,the operation of forming the guide portion 130 on the top of the stickermain body 120 may include:

applying a guide adhesive on the top of the sticker main body 120;

stacking a primer layer 134 a on the top of the guide adhesive;

forming a marking layer 134 b including a center line representing thecenter of the sticker main body 120 on the top surface of the primerlayer; and

forming a protective layer 134 c stacked on the top of the marking layer134 b so that the content provided by the marking layer 134 b ismaintained even under the application of external force.

While only the sticker main body 120 is retained on the top surface ofthe release liner 110, a guide adhesive is applied to the top of thesticker main body 120 to form the second adhesive. After forming theguide adhesive, the primer layer 134 a is printed on the top surfacethereof, wherein the primer layer 134 a is printed in such a manner thatit protrudes out of the free end 120 x of the sticker main body 120. Theprimer layer 134 a may be formed in the same manner as a paint primer.In other words, the primer layer 134 a is formed at the site where theguide film 134 is to be formed by using a silk screen printing process,etc., and then the marking layer 134 b and the protective layer 134 care stacked thereon successively, thereby forming the guide film 134.The primer layer 134 a is bound with the guide adhesive intended toserve as the second adhesive layer 132 but is separated from the releaseliner 110. Thus, even after the completion of the manufacture of theguide film 134, the primer layer 134 a is still separated from therelease liner 110.

After forming the primer layer 134 a, the marking layer 134 b is formedto print the center line or size mark on the top of the primer layer 134a. Finally, the protective layer 134 c is formed so that the markinglayer 134 b and the primer layer 134 a are covered with the protectivelayer 134 c. In this manner, the guide portion 130 is formed.

As can be seen from the foregoing, since the French nail stickerdisclosed herein includes a sticker main body having a guide portion, itis not required to scrape out the sticker main body manually when thesticker main body is detached from the release liner. Therefore, it ispossible to prevent the sticker main body from being damaged by thedetachment of the sticker main body from the release liner. In addition,when applying the sticker main body to a nail, it is not necessary tohold the sticker main body with a hand. Therefore, it is possible tomaintain the adhesion of the sticker main body uniformly and to preventthe sticker main body from being damaged by the adhesion of the stickermain body to a nail. Further, since the guide portion has a mark relatedto the center and size of the sticker main body, it is possible toselect a sticker main body suitable for the size of a user's nail withease and to attach the sticker main body to the nail with the aid of thecenter at once. Therefore, it is possible to prevent the shape of thesticker main body from being changed during the modification of theattachment of the sticker main body.
